I haven't ride one yet I will soon since I was one of the winners of the wing wind contest for the rapture II and i'm tham eager to try it.
I do believe that kite's future is defenitly conected to the bow style or something that will be develop from that whithout desregarding the C shape that I also believe that will remain untill the end of our days - diferent ways diferent styles and what a hell just enjoy the ride in the end of the day i'll be just happier.
